THE PROVEN POWER
OF LIQUID TITANIUM®

Engineered to be tough enough for heavy duty protection, Liquid Titanium® provides a frictionless barrier that stops soot and boosts efficiency — creating a longer engine life and larger profits. 

See the science behind the titanium shield:

  • Titanium is the world’s strongest lightweight metal. When liquefied, it molecularly bonds to engine surfaces to create a sludge-proof armor.
  • XRF scans confirm the durability of Liquid Titanium® — even after steam washing, titanium remains on engine parts.
  • Liquid Titanium® helps reduce sub-micron wear particles, improves oxidation stability, and enhances corrosion resistance.

24/7 Protection for 24/7 Operations

Turning over a project late can cost a large construction job millions. That’s why site managers trust Guardol® for better wear protection and longer engine life in off-highway equipment. To see the proven protection for yourself, watch our Caterpillar C27 Engine Teardown with Guardol ECT®. Switch now to stretch your drain intervals, so you can build more and repair less.

Crops Don’t Wait for Downtime

During planting and harvest seasons, even brief equipment downtime can have catastrophic effects. That’s why thousands of farmers trust their bottom lines to Guardol®. Engineered for extreme versatility, Guardol® allows nearly all farm equipment to run from dawn to dusk — so you can harvest on time, every time.

Proven Superior Oxidation Resistance

A lubricant’s resistance to oxidation determines how long the oil can effectively function before it must be replaced. In an average of three oxidation tests, Guardol ECT® proved superior resistance over similar competitor products — meaning you can spend less time changing your oil and more time getting to work.

Best-in-Class Soot Control

In tests that simulated deposits on the ring belt and piston under-crown areas, Guardol ECT® demonstrated better soot control from wear and soot-induced oil thickening. Plus, in a high-heat test that circulated an oil and catalyst mixture over a wire-wound depositor rod, Guardol ECT® had a lower deposit weight, indicating better deposit control — so you can shield your engine from soot abrasions.

Chat of long-term durability data

Unmatched Long-Term Durability

In a test that uses scuffing to show a product’s durability, Guardol FE® showed the highest level of wear protection, far exceeding the 31 hours-to-scuff limits required. This is a fired-engine test that shows how Guardol® is unmatched at preventing harmful metal-to-metal contact and the resulting damage known as scuffing.

The High Risks of Low-Cost Oil

Low-cost oils rely more on slogans than they do on science. So don’t trust their claims — trust the truth. Because an oil isn’t really low cost if it’s what’s causing your pricey repairs.
